CTE Resource Center - Verso

Virginia’s CTE Resource Center

Identify classifications of microorganisms based on cell wall structure.


Identification should include
  • the cell wall structure of gram-positive bacteria
  • the cell wall structure of gram-negative bacteria
  • the gram stain reaction and morphology of Staphylococcus and Streptococcus, gram-positive cocci vs. E. coli, and gram-negative rods.

Process/Skill Questions

  • What are the differences in the cell wall of a gram-positive vs. a gram-negative bacteria?
  • Why would a Gram stain be ineffective in staining a virus?
  • Why is the Gram stain such a rapid and cost-effective means for early diagnosis of bacterial infections?
  • How can the Gram stain reaction and morphology be used to differentiate Staphylococcus and E. coli?

The student will read, interpret, analyze, and evaluate a variety of nonfiction texts.
  1. Use critical thinking to generate and respond logically to literal, inferential, and evaluative questions about the text(s).
  2. Identify and synthesize resources to make decisions, complete tasks, and solve specific problems.
  3. Analyze multiple texts addressing the same topic to determine how authors reach similar or different conclusions.
  4. Recognize and analyze use of ambiguity, contradiction, paradox, irony, overstatement, and understatement in text.
  5. Analyze false premises claims, counterclaims, and other evidence in persuasive writing.



The student will investigate and understand relationships between cell structure and function. Key concepts include
  1. evidence supporting the cell theory;
  2. characteristics of prokaryotic and eukaryotic cells;
  3. similarities between the activities of the organelles in a single cell and a whole organism;
  4. the cell membrane model; and
  5. the impact of surface area to volume ratio on cell division, material transport, and other life processes.
